I've been pw for a year now & 1/2 of that 2stepping. Has anyone done extended research on the effects of diluted HF & long term exposure. While most everyone knows how bad the strong stuff is, what about the weak stuff. I dilute mine 1acid to 4water & then downstream. While not strong enough to burn skin or eyes what is it doing at this level. I watch the wind & overspray but you're still getting some on you/in you at some point. Most research I've done only talks about how deadly the raw form is. I did find something about excessive fluoride making strong but brittle bones. Wanted to see what education is out there cause I know most people 2stepping aren't suited up head to toe.
